When local police discovered “a large amount of ammunition, commercial fireworks, homemade M-class explosive devices,” and supplies to make fireworks in a West Springfield home, they called in the Massachusetts State Police bomb squad and a hazmat team to detonate the material, according to state fire officials.
West Springfield police responded to the home of a deceased, retired police officer on Monday to secure guns when they reportedly came across military ordinance, prompting a clean-out of the home.
“During the clean-out, the bomb squad discovered a large quantity of energetic material in a deteriorated state, believed to have been in the basement for years,” the Department of Fire Services wrote in a press release. “Some of the containers were marked and some were not.”
Authorities said the deteriorated state of the containers, the unknown stability of the fireworks, and the homemade devices created a “great risk to the occupants and to public safety.”
The bomb squad immediately began disposing of the materials, detonating them for several hours on Tuesday.
“The process of identifying and removing the materials took two days,” the department wrote. “Residents may have been aware of detonations on Tuesday night.”
